In other patients, if the wound does not heal for a long time, and the wound does not grow well for a long time, we also recommend that she must be checked for the presence of diabetes. For female patients, they are more likely to have genitourinary tract infections, so if they have recurrent urethritis, vaginitis or pelvic inflammatory disease, and after treatment, they have recurrent attacks, we also recommend screening for diabetes.
